Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Incorrect Privilege Assignment vulnerability in Modular DS modular-connector allows Privilege Escalation.This issue affects Modular DS: from 2.5.2 before 2.6.0.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

An incorrect privilege assignment vulnerability in the Modular DS modular-connector component allows authenticated users to escalate their privileges beyond what they should have. This privilege escalation flaw exists in versions 2.5.2 through versions prior to 2.6.0.

MitigationUpgrade Modular DS to version 2.6.0 or later to resolve the incorrect privilege assignment in the modular-connector. If immediate upgrade is not possible, review and restrict user role assignments as a compensating control.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Modular DS installation
    Locate and check the version of Modular DS installed in your environment. Common methods include: checking the software inventory, running 'modular-ds --version' or 'dsm --version' if CLI tools are available, or reviewing package manager records.
    Affected if The installed version is 2.5.2 or higher but lower than 2.6.0
  2. Verify modular-connector component presence
    Inspect the Modular DS configuration files or running services to determine if the modular-connector component is installed and active. Look for connector-related modules in the config directory or running processes.
    Affected if The modular-connector component is present and enabled in the Modular DS installation
  3. Review authenticated user role assignments
    Examine user account configurations and role assignments within Modular DS. Check which users are assigned elevated roles or permissions beyond standard user access.
    Affected if There are authenticated users with role assignments that may exceed intended privileges (this requires understanding your own role design)

You are affected if Modular DS version is 2.5.2 or higher but below 2.6.0 AND the modular-connector component is enabled AND there are authenticated users in the system.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Modular DS to version 2.6.0 or later to resolve the incorrect privilege assignment in the modular-connector. If immediate upgrade is not possible, review and restrict user role assignments as a compensating control.

Recommended fix Moderate confidence

2.6.0

  1. Verify current installed version of Modular DS modular-connector by checking the plugin/theme version in the WordPress admin panel or the installed files
  2. Backup the entire WordPress site and database before performing any upgrade
  3. Upgrade Modular DS to version 2.6.0 or later via the WordPress plugin repository, or upload the new version files
  4. After upgrade, verify the new version is installed by checking the plugin version in WordPress admin
  5. Confirm the privilege escalation vulnerability is resolved by testing that lower-privileged users cannot access higher-privilege functionality
